The experiment was carried out as split plot in time based on Complete Randomized Block Design with three replications and 12 treatments at Research Station, Faculty of Agriculture, Ferdowsi University of Mashhad, Iran, during growing season of 2010-2011. Treatments included: (1) mycorrhiza (Glomus mosseae), (2) biosulfur (Thiobacillus sp.), (3) chemical fertilizer (NPK), (4) cow manure, (5) vermicompost, (6) mycorrhiza + chemical fertilizer, (7) mycorrhiza + cow manure, (8) mycorrhiza + vermicompost, (9) biosulfur + chemical fertilizer, (10) biosulfur + cow manure, (11) biosulfur + vermicompost and (12) control. Vegetative parts of coriander were cut at 5% of flowering stage in two dates (19 May and 5 June). Results showed that the highest plant height (28 cm) and lateral branches (5.2) were obtained in combined application of biosulfur with cow manure treatment. The highest fresh and dry leaf weight, fresh and dry matter yield and stem dry matter weight were obtained in single application of chemical fertilizer. Single application of biosulfur increased leaf/stem ratio. The highest essential oil percentage and essential oil yield were observed in cow manure treatment (0.2% and 1753 g.ha-1, respectively). The maximum leaf/stem ratio were observed in the first cutting, while the highest lateral branches, stem fresh and dry matter yield, essential oil percentage and essential oil yield were obtained in second cut.

At the same time, 20 destructive quadrates determine and in addition of counting number of plants, leaf area index and dry weight of each species were recorded separately. By using data from previous section, hyperbolic functions were fitted. In these functions number of species serve as the independent variable, weight or leaf area was considered as the dependent variable. With the help of these functions and leaf dry weight of each species was determined for non-destructive quadrates at this stage. Relative leaf area at early season as independent variables and natural logarithm of individual plant weight at later season as dependent variable in a multiple linear regression was fitted to obtain the interspecies competition coefficients. Based on ln of weight of single plant equation the weed interference effects on the corn yield can be divided into two groups: inhibition (negative sign) and stimulation (positive sign). Among all weeds, night shade (Solanum nigrum L.), redroot pigweed (Amaranthus retroflexus L.) and lambsquarter (Chenopodium album L.) had positive effects on corn yield, respectively.

In this study long term stability of grin yield of wheat, barley, rice, corn and overall cereals in Iran were evaluated during a 40-year period (1971-2011). Stability analysis was conducted using two different methods. In the first method the residuals of regression between crop yield and time (years) were calculated as stability index. For this different segmented regression models including linear, bi-linear and tri-linear were fitted to yield trend data and the best model for each crop was selected based on statistical measures. Absolute residuals (the difference between actual and predicted yields for each year) as well as relative residuals (absolute residuals as percent of predicted yield) were estimated. In the second method yield stability was estimated from the slope of the regression line between average annual yield of all cereals (environmental index) and the yield of each crop in the same year. Results indicted that in wheat and barley absolute and relative residuals were increased during the study period leading to reduction of stability despite considerable yield increment. However, for rice and corn residuals followed a decreasing trend and therefore yield stability of these crops was increased during the last 40 years. The same result was obtained with the environmental index but in this method reduction of yield stability in barley was lower than wheat. Based on the results, yield and yield stability of cereals crops in Iran increased during the last 40 years. However, the percentage increase in stability is lower than that of yield. Application of nitrogen fertilizers was led to reduction in stability. Yield stability of wheat, barley, rice, corn and overall cereals was improved with increasing their cultivated area.During the last few decades cereals yield have increased drastically at the national level however, information about yield stability and its resistance to annual environmental variability are scare. In this study long term stability of grin yield of wheat, barley, rice, corn and overall cereals in Iran were evaluated during a 40-year period (1971-2011). Stability analysis was conducted using two different methods. In the first method the residuals of regression between crop yield and time (years) were calculated as stability index. For this different segmented regression models including linear, bi-linear and tri-linear were fitted to yield trend data and the best model for each crop was selected based on statistical measures.

In this study, the relationship between rainfed barley yield, temperature and rainfall were assessed with both simple correlation and iterative chi-square analysis for Eastern Azerbaijan in four districts (Tabriz, Maragheh, Sarab and Miyaneh). The iterative chi-square analysis identified relationships of low and high yield years to the maximum and minimum of temperatures and rainfall. The same patterns in all regions found in the relationship between rainfed barley yield and climatic indicators. In all regions,the main climatic factors limiting rainfed barley production were low,high and very high temperatures occurring during February (cardinal value rang, T min ≤ -10 °C to T min ≤ -20°C), before the onset of winter (cardinal value rang,T max≥15 °C to Tmax≥20°C ) and at anthesis stage(early May to early June) (cardinal value ranging, Tmax ≥ 25 °C to T max ≥ 35°C ) respectively. Cold nights (cardinal value rang, T min ≤ 10 °C to T min ≤ 20°C) and enough rainfall (cardinal value ranging, pp ≥ 5.8 mm to pp ≥ 10.6 mm ) led to increasing yield in ripening stage (early June to early August) and in the early planting respectively. In all regions, the anthesis stage was the critical time in which high temperatures and low precipitation led to yield loss.
